Weasel - an e-mail server for OS/2

Weasel is a free, open source, mail server supporting the POP3 and SMTP
protocols. You need a mail server if you want to set up your computer
to accept mail for multiple users. The SMTP component sends and
receives the mail, and the POP3 component lets users log in and fetch
the mail that has arrived for them.

An e-mail server would not be complete without some sort
of junk mail control. Weasel allows you to reject mail from a specified
list of hosts, and it lets you specify which hosts are allowed to relay
mail via your machine. Blacklists are supported. It also lets you define your own filters. You
could, for example, write a Rexx script that rejected mail that
contained certain keywords.

Username aliases are supported, and you can create an
alias that will expand out to a mixture of local and non-local
addresses.

Configuration
of the server is easy. Options, including operations such as addition
or deletion of users, are implemented by running the included Setup
program. For the traditionalists there is also a text-based VIOSetup,
but this does not support as many features as the PM-based Setup.

You
can also do remote configuration. That is, you can run Weasel on a server machine, but run Setup on a separate desktop computer.

You may configure Weasel either to host a single domain, or multiple mail domains.

Download

You can download the latest version of Weasel
from ftp.pmoylan.org/Weasel/. Source files can be found in the same directory. Weasel may also be found at the Hobbes archive.
Typically this is the most recent "major update", so it might be
slightly behind the version kept on the pmoylan.org server.

Optional extra: an IMAP4 addon for
Weasel Pro. This, however, is failing for some IMAP clients, so cannot be recommended at present.
